Q&A: What should be noted when using cuttings for connection? Answer: 1) The width of the cuttings should be consistent; mechanical tools should be used for this purpose ； 2) Plug connection is suitable for low-speed systems with an air duct wind speed of 10 m/s and a wind pressure of up to 500 Pa ； 3) Any areas where the joints are not tight should be sealed with sealing tape to prevent air leakage ； 4) Plug connections are best suited for ventilation and air conditioning systems that are not frequently disassembled.
1. The width of the cuttings should be consistent; mechanical tools should be used for this purpose； The 2-clip connection is suitable for low-speed systems with an air velocity of 10 m/s and an air pressure of up to 500 Pa ； 3. Any areas where the joints are not tight should be sealed with sealing tape to prevent air leakage ； 4-prong connections are best suited for ventilation and air conditioning systems that are not frequently disassembled
1. C-shaped and S-shaped cuttings should be rolled using specialized machinery. The width of the C-shaped and S-shaped inserts should match that of the duct connectors, and the extension at both ends of the C-shaped inserts should be 20 mm or more. 2. The side length of ducts connected using C-shaped flat cuttings or S-shaped flat cuttings should not exceed 630 mm. When used alone, S-shaped horizontal cuttings require fixing measures at the junction. C-shaped right-angled inserts can be used to connect branch pipes to main pipes. 3. The side length of the duct connected using C-shaped vertical cuttings and S-shaped vertical cuttings should not exceed 1250 mm. The junction between the S-shaped vertical splice and the duct wall should be riveted with a spacing of less than 150 mm. 4. The connection between the splice and the duct socket should be smooth and tight. The length of the horizontal cuttings should match the width of the duct, while both ends of the vertical cuttings should be extended by at least 20 mm each; after the cutting is completed, the ends should be bent. 5. C-shaped or S-shaped flat inserts should not be used for connecting rectangular aluminum ducts.
